Alyson Hannigan and her husband Alexis Denisof are now proud parents of a baby girl.

Satyana Denisof was born in Los Angeles Tuesday, March 24. “They’re very excited, and mom and baby are doing great,” a rep for Hannigan said.

Hannigan and Denisof, 43, met on “Buffy the Vampire Slayer” during the 1999-2000 season and were married in 2003. The girl also came as a birthday surprise for Hannigan, who turned 35 the same day.
